304 Not Modified should be expected because my client sends:
If-Modified-Since: Wed, 22 Nov 2006 01:00:00 GMT
If-None-Match: "12345"
I also suspect that mtime is the issue. The value of req.mtime is 0.0 just
before the meets_conditions call. Although I'm not familiar with the
internals of mod_python and Apache, I looked at Apache's
ap_meets_conditions, which uses current time as mtime if req.mtime is 0.
So meets_conditions is unusable until 3.3? Hmm....
BTW, when will 3.3 come out?
